Stating drop-proof structure includes baffle ring, heat insulation, and the baffle ring is arranged on the interface periphery, is set on the inner surface of the birdsmouth
There is mounting groove, the mounting groove has been embedded in O-ring seal, the O-ring seal and the mounting groove interference fit, the undertaking
Heat insulation is provided between mouth end and the baffle ring of the interface, the heat insulation and the birdsmouth end are fixed and connected
Connect.
The baffle ring is welded with the junction of the heat insulation.
The O-ring seal is T-shaped cushion rubber, and the T-shaped cushion rubber includes orthogonal ebonite position and flexible glue position, institute
The ebonite position for stating T-shaped cushion rubber is arranged in the mounting groove, shape, the size of the mounting groove respectively with the T-shaped cushion rubber
Ebonite position match.
The heat insulation is structure of the middle part with cavity.
The gap of 1-2mm is left on the left of the ebonite position and mounting groove, between the birdsmouth and the interface.
Hanger is symmetrically welded with the outer wall of the birdsmouth and the interface.
Two symmetrical hangers are respectively equipped with the outer wall of the birdsmouth and the interface.
Distance of the hanger apart from birdsmouth end or interface end is 1.2m.
The beneficial effects of the utility model are：Hanger is used to realize two carryings of socket joint steel pipe；There is provided heat insulation, and
It is hollow-core construction in the middle of heat insulation, deformation caused by the steel pipe partial overheat of the birdsmouth in welding is prevented, beneficial to steel pipe sealing
The maintenance of property；Baffle ring on the one hand be used for limit interface insert birdsmouth depth, on the other hand for heat-insulated block welding, will
Birdsmouth is fixed as an entirety with interface, so when hydraulic pressure is larger, pipeline will not also be washed open, is given used in buried
In water lines, pipeline leak can be prevented, eliminate only pier, construction more facilitates；Matched somebody with somebody using interference between T-shaped cushion rubber and mounting groove
Close, and further restriction has been done to the gap between ebonite part and mounting groove, between birdsmouth and interface so that meet bar
Two steel pipes of part are very good according to sealing after technology socket joint of the present utility model, and solving the excessive interface of cushion rubber can not insert
Enter, the technical problem of cushion rubber too small sealing difference, apply in Water and Waste Water Engineering, quality and economic effect are all fine, make up
The blank of steel pipe flexible interface connection.
